Channel 29 (2.3 MHz) checks the transmit power with talk power on. Also the
receiver sensitivity can be measured with the RF amplifier off. All remaining
channels (1 to 28) have the talk power off. This allows the two-tone transmit
signal to be viewed on the oscilloscope without the ripple being displayed.
All channels have the following enabled:
• USB/LSB/AM
• Emergency Call
• Selcall
• Two-tone
